Emily is a big lady. I don't think it's a big deal, except that she is always making contradictory statements. She makes off handed comments that imply she's insecure about her weight, but then she also says she embraces her body. My personal thought is that she's a binge eater. I had a friend that was really big (bigger than she was comfortable being) and she had these dietary restrictions about gluten, and she would always pack a healthy lunch, and she ate healthy. But she admitted that she binge eats at times. Like an entire bag of Doritos and an entire cake and ice cream. She'd "diet" until she felt hungry again, which could be days or weeks, and then do it all over. I'm not saying that Emily has BED, but she's taking in a bunch of calories somewhere.
Tamra seems to be fine with eating for the most part, so is Vicki, Gina, and Kelly. THis is just me, but as someone with a lot of eating problems and history of eating disorder, I HATE to see it on this show. I hate the ladies with obvious eating disorders, because it just reminds me of how hard it is to be normal, and how obvious it is when you aren't. Brownyn, Lisa Rinna, and Jackie from NJ are currently the folks I fast forward because of how they always have to make a big deal about food and eating.
